JUDSON K. PURINTON, OF DALLAS CENTRE, IOWA.

AGRICULTURAL BOILER AND FEEDSTEAlV|ER.

SPECIFICATION forming part of Letters Patent No. 264,101, datedSeptember 12, 1882.

Application tiled March 18, 1882.

T o all whom it may concern:

Be it known that I, .TUDsoN K. PURINTON, ot' Dallas Centre, in thecounty of Dallas and State of Iowa, have invented au Improved PortableSteam-Generator and Feed-Cooking Apparatus, of which the following is aspecification.

'Ihe object ot' my invention is to save time and labor by theconstruction ot' a combined furnace and boiler and completesteam-generator, and to provide a complete apparatus that is speciallyadapted for heating water and cooking feed in barrels or other suitablevessels that may be placed in various places convenient for the purpose.

It consists in forming a base-plate and furnace-grate integral with eachother, as hereinafter fully set forth, in such a manner as to adapt acombined vertical boiler and furnacechamber to be simply placed over thecombined base and grate to produce a complete boiler-furnace andsteam-generator in an instant in the stable-yard, field, on Whereverdesired, to be expeditiously put in' operation and readily and safelyused by any person ot' ordinary intelligence to advantageouslyaccomplish the results contemplated.

My accompanying drawing is a perspective view of my base and furnacegrate and boiler combined, and illustrates the construction, op-

eration, and utility of my complete invention.

A represents my base in the form of a circular plate, that is open inits center, and has a series ot' posts, l 2 3, formed integral therewithin such a manner that they incline in wardly to coliform with the innersurface of the upright boiler thatis to rest upon the base when in use.

B represents a f n mace-grate formed integral with the base A and postsl 2 3, and extends horizontally between the top ends of the series ofposts, to be thereby retained in an elevated position in such a manneras to produce a vacant space and ash-pit underneath it in the completefurnace when the boiler is placed over it.

G is the outside wall of a boiler of common form. It is preferably madeof galvanized (No model.)

iron, uniform in diameter, and of any size desired.

D is the inside wall ofthe boiler, ot' tapering or conical form. It isalso made ot' sheet metal, preferably doubled over the wall A at itsbottom, and riveted and soldered fast thereto, to produce a water andsteam tight connection. At its top and small end it extends through theclosed top ofthe boiler and terminates in a tine, E. The annular chamberbetween the walls A and D forms a water-reservoir at its lower endimmediately around the combustion-chamber of the furnace, and the upperportion a steam-chamber surrounding the upper portion of the inner wall,D, through which the products of combustion pass u pward. The entireinner Wall is thus utilized as water and steam heating surface.

f represents an adjustable door, through which fuel is introduced todrop down upon the furnace-grate.

g represents a sat'etyvalve.

lz represents a jointed and flexible steamednction tube, through whichsteam is conveyed into a barrel to cook feed, (as indicated by a figurein broken lines,) or to any place whe-re the steam may be desired.

represents a stop-cock and water-gage. 7c is an opening formed in thelower edge of the boiler to extend through both the walls A and D, asrequired, to provide a draft for the furnace.

m represents a. detached and adjustable door, adapted to close, orpartly close, the opening k, as required, to regulae the draft of thefurnace.

In the vpractical operation of my invention thus constructed, Isimplyplace my combined base and furnace-grate iiat upon the ground whereverdesired, and then set the vertical boiler over the elevated grate sothat the inclined inner wall will engage the inclined series of postsand the bottom edgerest tirmly upon the horizontal circular plate,asshown in mydrawing. I then till waterinto the boiler through thesafety-valve or some other suitable feed device, and start a tire on thegrate. Steam will then be rapidly generated to be applied through theflexible eduction-tube for l elinecl inner wall, D, a smoke-flue, E, atits 1o cooking feed, heating W21te1,oi1 any other` purtop, and anopening', k, at its bottom, and :L pose for which it can be utilized.iexible steain-eduetion tube, 7L, adapted to en- I claim as my inventiontei1 2t barrel, substantially as shown and (le- 5 The improvedsteam-generator and feedscribed, to operatein the manner set forth.
